Thomas Midgley Jr. was a brilliant but star-crossed inventor. He invented leaded gasoline to prevent engines from knocking. Unfortunately, it lowered the IQs of people exposed to it. He also invented Freon as a non-toxic refrigerant. Unfortunately, it destroyed the ozone layer. Late in life, he contracted polio and devised a system of ropes and levers to pull him out of bed. This backfired as well, causing his death by strangulation.
